Vitrakvi® Oral Therapy for NTRK Gene Fusion Cancers

What Vitrakvi Is and How It Works

Vitrakvi® is larotrectinib, an oral targeted therapy for solid tumors with an NTRK gene fusion. It blocks TRK signaling that drives cancer growth. You can access Canadian pharmacy options with US delivery from Canada, which may help if you pay without insurance.

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

This treatment is a selective TRK inhibitor. It binds to TRKA, TRKB, and TRKC proteins and may slow or stop signals that help cancer cells survive. It is tissue agnostic, which means eligibility depends on the tumor’s biomarker rather than its location in the body. The capsule and oral solution options can support adults and pediatric patients who meet genomic criteria. Refer to the Cancer With Ntrk Gene Fusion overview for context on testing and care pathways. For regulatory background, see how the Larotrectinib FDA approval established a biomarker-defined indication.

Who It’s For

This medicine is for adults and children with solid tumors confirmed to have an NTRK gene fusion. It may be considered when tumors are metastatic or cannot be surgically removed, and when there are no satisfactory alternative treatments or the disease has progressed after prior therapy. Your prescriber will confirm eligibility with validated testing and clinical history. The Larotrectinib indication is not limited to one organ; examples include salivary gland, thyroid, soft tissue sarcoma, and lung cancers diagnosed with an NTRK fusion.

People with known TRK resistance mutations, severe liver problems, or certain uncontrolled neurologic conditions may not be candidates. Discuss pregnancy, plans to become pregnant, or breastfeeding with your clinician before starting therapy.

Dosage and Usage

Larotrectinib is typically taken twice daily. Capsules are swallowed whole with or without food. The oral solution is measured carefully using the provided device and taken by mouth. Pediatric dosing and some adult dosing may be based on body size. When the clinical situation is complex, the prescriber will tailor the regimen. If you are unsure, follow the official instructions and ask your care team.

Do not change your schedule unless your prescriber tells you to. If side effects occur, contact your clinic. They may interrupt treatment or adjust the plan. See the Vitrakvi label for complete dosing directions and dose modification guidance.

Strengths and Forms

Common presentations include capsules and an oral solution. Published strengths for the capsules and the liquid are available in official sources. Supply options can vary by market and manufacturer packaging. Availability may change based on pharmacy inventory.

• Capsules are available in more than one strength for flexibility.
• An oral solution is provided for patients who cannot swallow capsules.
• Confirm the exact strength and formulation on your prescription label.

If your prescriber plans a formulation switch, your pharmacy will counsel you on correct measurement, timing, and how to continue safely.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to the next scheduled dose. If it is close, skip the missed dose and resume your normal routine. Do not take two doses at once to make up for a missed dose. If you vomit after a dose, do not repeat the dose; wait until the next scheduled time. Ask your clinic for personalized advice if missed doses happen often.

Storage and Travel Basics

Keep this medicine in its original container with the label intact. Protect it from moisture and excessive heat. Keep out of reach of children and pets. For the oral solution, use the dispenser from the package and keep the bottle closed tightly. Do not mix the liquid with other medicines unless told by a clinician.

When you travel, pack your supply in a carry-on, along with your prescription label and a copy of your prescription. Store it according to the label during travel, and avoid leaving it in a hot car. If your trip includes time zone changes, keep taking doses about 12 hours apart and consult your prescriber if you need help adjusting the schedule. Our site supports Canada sourcing and offers guidance so you can plan refills ahead of time.

Benefits

This targeted therapy focuses on tumors driven by NTRK gene fusions, regardless of tumor origin. Oral dosing can be convenient for many people. Having both capsule and liquid options may help patients across a wide age range. The class can offer a treatment route even when other options have been exhausted. Patients and caregivers may appreciate the consistent twice-daily routine that simplifies planning.

Side Effects and Safety

Common effects may include fatigue, dizziness, nausea, vomiting, constipation or diarrhea, cough, and abdominal pain. Some patients have changes in liver tests, anemia, or low white blood cells. Dizziness can increase fall risk; take care when standing up or operating machinery until you know your response.

• Liver effects: your prescriber may monitor liver tests regularly.
• Neurologic effects: dizziness and gait changes can occur.
• Gastrointestinal effects: nausea, vomiting, constipation, or diarrhea may appear.
• Musculoskeletal effects: pain or weakness may be reported.

Serious risks are less common but can include severe liver injury, neurologic effects that impair coordination, and hypersensitivity reactions. In growing children, your team may monitor for effects on bone growth plates. Call emergency services if you experience trouble breathing, swelling of the face, or severe rash. Patients who also take medicines that lower blood sugar or blood pressure should watch for additive effects such as lightheadedness.

Drug Interactions and Cautions

Larotrectinib is metabolized by CYP3A. Strong CYP3A inhibitors or inducers can change blood levels. Your clinician may adjust plans if you use such medicines. Avoid grapefruit products unless your prescriber says they are safe with your regimen. Patients with significant liver impairment may need additional monitoring. The prescribing information and the Larotrectinib FDA approval materials discuss these interactions in more detail.

Tell your clinician about all medicines you take, including over-the-counter drugs, herbal products, and vitamins. Discuss pregnancy prevention and contraception during treatment and for the recommended period after the last dose. Breastfeeding is usually not advised during treatment; follow the official label for timing.

What to Expect Over Time

Responses vary, and your care team will guide imaging and lab monitoring. Some people notice improved symptoms over time, while others may not feel different even when scans show disease control. It is important to take doses as prescribed. Set reminders and use a simple routine to reduce missed doses. Keep all clinic appointments for monitoring and evaluation. If side effects appear, share details with your team so they can support you promptly.

Compare With Alternatives

Other targeted options exist for specific gene alterations, though they are not substitutes for NTRK-directed therapy unless your biomarker changes. For RET fusions in certain tumors, some patients may use Retevmo. For ALK- or ROS1-positive lung cancers, prescribers may consider Xalkori. Your biomarker results and treatment history drive these choices. Review our broader Cancer range and speak with your clinician about the right plan.

Patients sometimes search to Buy Larotrectinib when their branded stock is limited; your prescription will guide which product can be dispensed.

Patient Suitability and Cost-Saving Tips

Adults and pediatric patients with a documented NTRK fusion may be candidates when surgery or other treatments are not suitable. People with active, uncontrolled neurologic issues or severe hepatic impairment may need different plans. Discuss your medical history and all medicines with your prescriber before starting.

• Refill timing: set alerts so you request your refill before running out.
• Multi-month fills: ask about 60- or 90-day quantities if appropriate.
• Formulation fit: choose capsules or liquid based on swallowing and dosing needs.
• Travel prep: keep a copy of your prescription for security checks.

Patients who compare Larotrectinib cost without insurance often explore multi-pack options to reduce per-fill fees. When switching pharmacies, keep your current bottle and measuring device for reference until the new supply arrives. Our catalog also includes biomarker-related education such as Solid Tumor resources and public-awareness pieces like World Lung Day Raising.

Questions to Ask Your Clinician
